The service is requesting $194.1 billion, including war funding -- a 14 percent increase from the previous request, for more personnel; operations and maintenance; and research and development, among other accounts.

The request would increase the size of the active-duty end strength to just over 329,100 airmen, an increase of 4,000 airmen over the previous year, according to the documents. The Air National Guard is requesting another 500 airmen; the Air Force Reserve wants another 200 airmen.

"We continue to focus on addressing gaps in critical career fields to include intelligence, surveillance and reconnaissance; remotely piloted aircraft; and cyber career fields," the budget request states. That includes ramping up training pipelines for those career fields, it added.
